@JulianHols Hi, were you getting any sound or pictures when the problem started (when the tv was power cycling). After tapping, if you are not getting any sound or pictures, you may need to tape multiple pins. I will suggest disconnecting the ribbon cables one after the other on the left and right to see if you get half a picture or at least some sound.

@AndersonSilva-ny1bf Please, if you still have a warranty, it will be best to contact them to resolve it for you. Don't void the warranty.

@@youaboomer5102 😁 I am happy it all worked out.

@OfficialMileSanta You are welcome, and thanks for subscribing.

@@gillesrodrigue Sorry for the late response. Please can you clarify what you mean by pressing down on them. Did you test the backlight strips before installing them? If you need to hold down something to keep them on, it may be you have a loose connection.

@@GidFix-pl3lg can you tell me what kind or make of the two side adhesive tape you use i think tht's my problem. All strip are working well

@gillesrodrigue It was a scotch mount double-sided mounting tape (Extreme). I don't think the tape makes a difference. Check where the strips connect to form one strip. Usually, that comes apart when one is trying to align the strip.

@@ClutchTacticsGaming Glad to hear that.

Which country are you located? You can easily get one on Amazon or Aliexpress. Just type LED Backlight Tester in the search engine.

@@GidFix-pl3lg Thanks. Bought one on Amazon. Arrived next day. Should be set. Now just waiting for the backlights.

@@frugalenterprises8990 Great to hear. All the best in your repair. Just be careful with the LED Panel and you will fix it.

Clicking sound could be a power board issue. Does your TV keep restarting?

@@GidFix-pl3lg yes tv restarting

@@bhawanjitsingh6283 Your TV is quite huge. If you are able to open the back, try testing the power board with a multimeter but without a connection to the tv panel from a motherboard. This is one test to eliminate the problem.

@user-dt3vq5lu1p Comments like yours make me happy. I'm very glad you could get it working again.

So after you put the tape how many months can last you the tv?

@@mduduzishabalala2348 Its been close to a year now and the tv is still working.

@@GidFix-pl3lg wow that's great man

I also fixed two tv Samsung 58 " is working

@mohamedshafi9651 I'm glad it was helpful. Thanks for your comment.

@@mohamedshafi9651 I'm glad it was helpful. Thanks for your comment.

Glad it was helpful. Thanks for watching and subscribing.

@@javierbustos236 You are welcome. All the best.

@@GidFix-pl3lg I did it. Tv works like new. Thank you

Yes, exactly. I had to initialize it because that was the only option available, which automatically resets the ps5.

I searched on ebay and got one. You could also look around the black market on facebook for a cracked screen one.

You can get them on eBay or AliExpress

Hi, thanks for the detailed explanation about your tv and sorry for the late response. Your issue is quite unique and may be a problem from one or multiple sources. Lightning could have partially affected the power supply or both the power supply and panel itself. Usually, i would try to do some elimination. Since you haven't disassembled, it could be best to use it as it is. However, it may eventually stop working. The first thing i would try is to disconnect the motherboard from the powerboard, and switch it on and test the voltages that feed the motherboard with a multimeter. Ensure the tv has been off for a while so that you can provide the same conditions to replicate the fault. If the voltages fluctuate several times before a constant voltage is achieved, then it may be the powerboard. My reservation is with the horizontal lines that show up every time. That could mean nothing or could be an indication of a panel board or panel issue. You could also listen very closely to the TV if there are any buzzing or unfamiliar sounds when the tv is power cycling. If the powerboard gives constant voltage after disconnecting the motherboard, then try disconnecting the panel ribbon cables from the tcon board or motherboard (depending if this tv has a tcon board or is built into the motherboard), switch it on and test the voltage for fluctuations. If it doesn't fluctuate, then the panel driver board or panel itself could be the issue. If you don't have a multimeter, do the above and see how the backlights behave. I hope this can help you for now. Thanks.

I'm glad it worked. The TV is still working perfectly to date. Yes, there are lines but only visible when very close to the TV.

Thanks for subscribing and sharing your knowledge. Much appreciated.

The spot i taped in the video may be different for your TV. You may have to try taping different spots to get it working. You will need lots of patience to figure the right pins to tape.

Sorry for the late response. The situation is complex. You didn't mention anything about the TCon board. Was that also replaced? Usually, a vertical blank line may be a faulty tcon board, or faulty panel, or incompatible motherboard. A few things to check are the part number of the motherboards and ensure they are the same. You may want to use all the new boards you received together in the TV, instead of mixing them up with your old parts. One last thing, when you put your old boards back, I assume you don't have a display but have sound, did you check with a flash light to see if those vertical lines showed up? The vertical lines may have been there before the new parts came. Let me know how it goes.

As far as I understand there’s no Tcon board on this model. Just a power board, main board, and “wireless board.” Regardless yes I did initially replace all three boards with the ones they sent. Backlight works but no picture. When I put the old main board back in, I get the picture with two blank lines. Their tech department responded to a similar question I asked above and said the problem is that my LED has “shorted drive ICs”, which then caused a failure on my power board, and therefore it is not reparable.

@@marshallsanchez2070 My mistake, I got this mixed up with another TV model and thought it had a TCON Board. What baffles me is that the new board does not give the two black lines. The issue should be replicated with any motherboard if the issue is from the shorted drive ICs. But yes, as i said in my last response, vertical lines can be an issue in the panel.

Yeah that’s what I assumed as well- that interchanging the old main board for a new one should have, at worst, the same results. I do a lot of electronic repair and I definitely hit my “more time than it’s worth” limit on this. I just bought a new one of the same model- because now at least I have spare parts! Thanks so much for your replies and your video. It’s all incredibly helpful.

Try disconnecting the motherboard cable from the power supply board. Then, plug it in and use a multimeter to check the output voltage to the motherboard on power supply to see if there are voltage fluctuations. If the voltage is stable, then it's likely your motherboard causing that.

Did you mean lining up new led strips to the TV or lining up individual led lights on a strip for soldering?

Basically, it depends on the tv. You can look at the old led strip and see how they align before you take them off. Usually, I leave one of the old strips for my reference, and after I have lined up and connected at least two new strips, I take the last strip off. Just watch out for groove marks and screw holes that align with the led strip. Hope it helps.

Does the standby light stay on when you use the remote? Does it flash a number of times? Check your remote batteries to ensure the remote is working. Or you can try directly turning on from the tv. You should get some response by looking at the standby light.

Hi, that is not normal. Did you have tape on the ribbon pins before checking the voltage at ck1 or ck2? If not, check that flex cable for damage. It could also be a faulty capacitor on the drive panel. You could use continuity mode on a multimeter to check them.

Thanks for the encouragement.

I had that issue as well and its because you are covering more pins than needed. Continue to narrow the tape. You need lots of patience in trying out different pin combinations. You may even have to cover just one pin or several pins at different locations. This is a well known issue with this TV. Hope it helps.

@@GidFix-pl3lg aaah ok that's good to know. Even in several places. Do you think it can happen in two sides of the panel too?

@@MrSahle Yes it is possible. Shorts in the Panel can happen on a single line or several lines depending on the extent of the problem.

@@GidFix-pl3lg Hello. Thanks for the nice content. I want to ask a question. There is voltage on ck1 and ck2 on the left side, but not on the right side. Is this normal?

Not much of a difference in my opinion. But check your powerboard schematic to see what voltage value is required at the pins. If the tv is completely dead but you are getting these voltages from the powerboard, then its likely the motherboard has the issue. Also Test the tcon board for any output voltage. Hope it helps.

Tiktok? What is that?

Thanks for the comment. You are right. However, I usually want to make it very detailed so that anyone can follow the process and fix their TV. I will definitely try my best to make it shorter.

Krys....y3 steady.

I am not a God sir but i am glad i could help. Take care.

Thanks for the question. Unfortunately, this short seems to be in the panel or screen so it makes it difficult to do such a test.

Thank you.

Thanks for the encouragement. Appreciate it.

Are you referring to the ribbon that connects the left and right panel driver boards?

howd you go

I am assuming you are taping the connector at the right side of the panel board. Do you get any sound in any of your scenarios? Disconnect the ribbon cable to the motherboard and check if the backlight will still blink when turned on. If you have a multimeter, you could check if your panel board has voltage coming to them.
